Change Font Family

Hi,

I am trying to change all my body text on my site to Century Gothic…I have read various tutorials and currently my css looks like

body {
color: #6B6B6B;
word-wrap: break-word;
line-height: 1.7;
font-size: 15px;
font-family: “Century Gothic”;
}

but when I refresh my pages, the font has not changed…Unsure as to what I am doing wrong…Sorry I am not too hot on coding!

Thanks
